Abstract
Time-and-polarization-resolved acoustic microscopy with an improved-spatial-resolution line-focus transducer of simply reduced active element width is applied to characterize surface and subsurface cracks. From acoustic images obtained from scanning cracks in different transverse directions and orientations, the presence, orientation, length and depth of cracks are induced.
